The purposes of this study were to explore amount of time use for paid work house work, child caring and leisure spent by adults and to explain its influencing factors. Tobit model was used to analyze the factors of time use because the amount of time use was a limited continuous variable. The results of this study were as follows: 1) Amount of time spent for paid work per day by adults was found to be 349 min. for men and 185 min. for women. Amount of time spent for house work was found to be 19min. for men and 155 min. for women. Amount of time spent for child caring was found to be 5min. for men and 40 min. for women. Amount of time spent for leisure was found to be 285 min. for men and 266 min. for women. 2) Time use for paid work was found to be significantly influenced by householder, age, time limit and paid worker for men and householder, time limit and paid worker for women. Time use for house work was found to be significantly influenced by age, time limit and paid worker for men and householder, age, marital status and paid worker for women. Time use for child caring was found to be significantly influenced by presence of kids and marital status for men and house, presence of kids, marital status and paid worker for women. Finally, Time use for leisure was found to be significantly influenced by car, time limit and paid worker for men and house, presence of kids, marital status, time limit and paid worker for women.

Objectives: Construction workers are exposed to various hazardous substances simultaneously. However, little is known about the exposure hazards in construction industry. This study was aimed at identifying the risk of exposure hazards among construction workers. Methods: The expert survey (n=29) was conducted, including construction industry health managers (n=11) and work environment monitoring experts (n=18), on exposure probability, intensity and risk of hazardous substances by construction occupations Results: The exposure hazards of 30 construction occupations were identified and summarized through a literature review and expert survey. The most prevalent hazards were in order of noise, awkward posture, heat/cold, crystalline silica, cement/concrete dust, metal fumes, and volatile organic compounds. The hazards with highest risk score(over seven points) at construction occupations were noise(formwork carpenter, concrete finisher, rebar worker, demolition worker, driller/rock blaster), hazardous rays(welder), heat/cold (earthworks, formwork carpenter, rebar worker, concrete placer, scaffolder), awkward posture(bricklayer, caulker/tile setter, rebar worker) and heavy lifting(bricklayer, rebar worker). Among construction workers, the job types with the highest risk of exposure to carcinogens, and in which occupational cancer has been reported, were in order of stonemason, concrete finisher, rock blaster, welder, insulation installer, painter, scaffolder, plant worker and earthworks in order Conclusions: Systematic research and discussion on occupational disease among construction workers and its various hazardous factors are needed to establish job exposure matrix for facilitating standard for promptly processing the workers' compensation.

To reduce a high fault current, neutral ground reactors (NGR) were installed in the Korean substation. Current with several harmonic components flows in a NGR due to load unbalance in normal steady state and magnetic fields with several harmonic components are also generated around a NGR. As results of study, we found magnetic fields around a NGR in Korean substation included two harmonics, 180Hz and 540Hz. Magnetic fields of 180 Hz increased 3 times more current density inside a worker near a NGR than same magnitude magnetic fields of 60 Hz. We know a worker near a NGR may not meet ICNIRP guideline of 10(mA/$m^2$) due to several harmonic components.

The regulatory recognition, regulatory approval, and observance for employer, inspector, and worker groups were investigated for the Korean measurement system in working environments. The employer, worker, and inspector showed an agreement of 90~97 % for the measurement of working environments. This survey showed that the measurement system of working environments has been settled in Korea. However, this survey showed an agreement of 81~87 % for reporting the results of working environment, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement. The employer recognized well for the measurement of working environments, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement, but the employee did not recognize well them as much as the employer did. Thus, the improvements for the recognition for involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement by the employee are needed.

This study was performed to evaluate the worker exposure to asbestos fibers in automobile repair shop and brake lining store from August 11 to October 21, 1988. In addition, the exposure of general population near the brake lining store was also evaluated. Results of this study were as follows. 1. Worker exposure level to asbestos fibers in automobile repair shop was 0.1 fibers/cc, well below the Korean standard of 2 fibers/cc, and a half of the U.S. standard of 0.2 fibers/cc. 2. Average worker exposure level to asbestos fibers in brake lining store was 0.35 fibers/cc, which was within the Korean standard of 2 fibers/cc, but exceeded the U.S. standard of 0.2 fibers/cc. 3. Worker exposure levels during the removal of brake dust with the compressed air blowing and the dry brushing were approximately 4 fibers/cc and 0.2 fibers/cc, respectively. During grinding of brake linings with sand paper, asbestos exposure level was 0.3 fibers/cc. 4. Ambient asbestos concentrations outside the brake lining store were 0.1 fibers/cc at the distance of 3-4 m, and 0.01 fibers/cc at the distance of 30 m.

Background: Functional capacity evaluations (FCEs) are designed to systematically assess the capacity to perform work-related tasks and to determine worker's ability to return to the previous job following work-related injuries. These evaluations may be rated either by clinician or worker. There has been a lack of consensus between the two scoring methods. Objects: This study aimed: 1) to confirm if the data are fit to the Rasch rating scale model and 2) to investigate the item-level concordance rate between the ratings of clinician and injured worker of the FCE. Methods: A cross-sectional study was conducted with a sample (n=124) of a rehabilitation program with the Occupational Rehabilitation Data Base for workers with low back pain. The functional capacity evaluation at admission and discharge was administered to clinicians and workers. The data were analyzed using both classical test theory-based Pearson's r and intra-class coefficient followed by item-level analysis with Rasch rating scale model. Results: All items of the FCE, except sitting items rated by clinician at admission and handling items rated by both clinician and worker throughout admission and discharge, were acceptable fit statistics with minor out of ranges for a misfit criterion. This may indicate that the items of the FCE overall fit to the Rasch rating scale model. Few problematic items responding differently to clinician and worker both at admission and discharge were detected with the differential item functioning analysis despite the excellent concordance rate using the two conventional statistics-sitting and handling items at admission and handling item at discharge. Conclusion: The item-level speculations using Rasch analysis of the FCE demonstrate that the ratings of clinician and self ratings of worker were psychometrically acceptable though there was an apparent discrepancy between the raters both at admission and discharge.

본 연구는 사회복지 이용시설에 근무하는 사회복지사를 대상으로 인식론적 신념과 지시적 실천정도를 탐색하였다. 인식론적 신념은 지식에 관한 이론으로서 사회복지사에게 실천행위의 근거를 제공해 준다는 의미에서 사회복지실천과 관련성을 찾을 수 있다. 본 연구에서 인식론적 신념은 객관주의와 구성주의 인식론으로 분류하여 분석하였으며, 지시적 실천정도는 Rothman 등이 제안한 클라이언트에 대한 사회복지 실천유형을 근거로 구분하였다. 따라서 본 연구의 목적은 사회복지사의 인식론적 신념이 지시적 실천정도에 어떤 영향력을 미치고 있는가를 밝히는 것이다. 분석결과 사회복지사의 인식론적 신념은 객관주의 인식론에 비해 구성주의 인식론이 상대적으로 높게 나타났으며, 객관주의 인식론은 사회복지사의 지시적 개입에 정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 사회복지 실천과정의 복잡성과 독특성을 고려할 때 사회복지사에게 다양한 인식론적 입장이 필요하다는 것과 객관주의 인식론에 대한 성찰을 요청하고 있다.

Importance of quality control is gradually increasing in the construction. And the reber work is very important things which influence in safety and durability of the building and accounts for about 9.8% of the total cost. Although reber work is important, quality control of the rebar work is still performed by attitude and experience of worker. Therefore, it is very important to quality achievement effort and quality standards recognition of rebar worker for quality sophistication in the construction. Some papers have dealt with the quality control in construction. But there was no study for actual conditions of quality standards recognition of rebar workers. The purpose of this study is to survey the actual conditions of quality standards recognition of rebar workers and to analyze difference of consciousness of administrator and worker. The result are : there id difference of consciousness of worker and administrator, workers work without knowing quality standard.
